Dylan Curran downloaded all of the data stored on him by Facebook and Google
Google's data archive was almost ten times larger than scandal hit Facebook's
It dated back to 2008 and revealed a level of detail that shocked the IT expert
He laid out the extent of the private information held on him in a series of tweets
Facebook has hit the headlines in recent weeks over its handling of your private data, and now the shocking extent of information held by Google has been revealed.
In a series of tweets, one IT expert has laid out exactly what the search giant knows about him, dating back to 2008, which he describes as 'preposterous'.
It ranges from every place he visited in the past year to every website he clicked on, and even contained files deleted from his Google Drive cloud storage account.
The news comes in the wake of the Cambridge Analytica scandal, which saw a Trump-affiliated firm obtaining data on 50 million unsuspecting Facebook users.
This information was used to target voters in the US, based on psychological profiling, with political adverts spreading disinformation.
Web developer Dylan Curran, based in Waterford, Ireland, decided to download both his Facebook and Google archives on Saturday.
The data held by the world's most popular social media site was fairly large, at around 600mb, equivalent to roughly 400,000 Word documents.
But this paled in comparison to Google's data file, which was 5.5gb, almost ten times larger. This is around the same size as three million Word documents.
Sharing his findings on Twitter, in a post retweed more than 150,000 times, he said: 'Want to freak yourself out? I'm gonna show just how much of your information the likes of Facebook and Google store about you without you even realising it.'
